High-Temperature Wire Applications and Common Uses

High-Temperature Wire Applications and Common Uses

An environment with harsh conditions can benefit from using high-temperature wire, especially in ambient places and have high temperatures. It is crucial to choose the proper high-temperature wire that’s right for the environment’s condition. That is so that its lifespan would not be affected or altered. The high-temperature wire applications for a selection of appliances and products will make sure that the temperature range for its design will adhere and that there will be no failures in the product. 

Features of High-Temperature Wire

A cheap high-temperature wire can have a reading of 150 degrees Celsius or higher. Sometimes, you can also find high-temperature wires with a 90 degrees celsius rating. High-temperature wires can either be a single conductor or multi-conductor. The most common conductor for high-temperature wires includes copper plated, nickel-coated copper, or tinned copper. Some high-temperature appliance wires also include an additional jacket made from fibreglass or K-fiber material. The 2 key components that can guarantee a high-temperature wire can be suitable for its application are ampacity and temperature rating.

Ampacity is calculated by the maximum current that an insulated conductor can withstand without going beyond jacket temperature and insulation limitations. For example, if the high-temperature wire is undersized, it can produce heat that exceeds the circuit load. 

Temperature rating is defined as the wire’s maximum continuous temperature that can withstand its entire lifetime. If the temperature rating doesn’t fit with the environment and ambient, then the wire’s lifespan will be affected. 

Applications of High-Temperature Wire

TGGT

TGGT (Teflon Glass, Glass Teflon) – utilized in commercial or industrial heating equipment up to 250C. It’s used for heaters, furnaces, ovens, and kilns.

SRML/SF2/SFF2

SRML (Silicone Rubber Motor Lead) – This product is employed in automotive motor leads, fixtures, or electrical equipment not exceeding 150C or -65C. Other applications include high wattage units, sun lamps, and therapeutic devices. SF2 – almost like SRML, this coarse stranded appliance wire is employed in motor leads and fixtures but can handle a better temperature, not exceeding 200C. SFF2 – This product includes a lower temperature rating than SF2 and can’t exceed 150C. However, it’s a more flexible version of SF2 and SRML because of its higher strand count.

MGT

MGT (Mica Glass Tape) – utilized in hot temperature environments like industrial ovens up to 538C Non UL or 450C UL. It’s employed in commercial, industrial, and household ovens, cement kilns, and electric heaters.

SRK

SRK (Silicone Rubber K-fiber Jacket) – supported Style 3410, it’s a flex strand lead and appliance wire utilized in the motor leads not exceeding 200C. It is often seen getting used for booster melting systems for glass plants, steel mills, and other harsh environments.

FEP

FEP (Fluorinated Ethylene Propylene) – Used mainly in high temp environments not exceeding 200C, which require additional protection from moisture or abrasion. It’s common to determine this high-temperature wire in chemical, electrical, and medical applications.

Final Words of Advice

As we have mentioned in the text above, high-temperature wires can be used in environments that have harsh conditions and elevated temperatures. These applications may include internal wiring of assorted appliances such as refrigerators, dryers, lighting fixtures, ovens, air conditioners, and electrical ranges. They are also used in different manufacturing plants and factories. Check out our different wiring products for your required applications.
